It’s a game many companies play. They post jobs, interview some candidates, then say to the government they can’t find anyone to fill the role.... (which is total bunk) then they go out and get a H-1b visas worker.
This is true for some, but only for limited numbers. The total number of H1b is way smaller than the “openings” listed.
You are correct. I’ve been through lots and lots of these “job postings”.
It’s a waste of time with most of them.
